.SYNOPSIS...A period of calm and cloudy weather will persist until
midweek. This Wednesday will see a storm system quickly pass over
the region bringing snow and colder temperatures. A period of very
cold weather will settle across Nevada after the passage of the
storm system.


.SHORT TERM...Dry and calm weather will persist over Nevada Today
and Tuesday as a ridge remains in place over the area. A
significant amount of upper level moisture will move over the
ridge producing cloudy conditions across the northern portions of
the state. A robust and quick moving storm system will pass over
Nevada this Wednesday bringing a round of snow showers. The low
valleys in Humboldt county may experience rainfall at first but
with the quick intrusion of cold air it should quickly shift to
pure snow. The system should produce accumulations of 1 to 3
inches in the northern NV valleys and 1 to 2 inches in central NV
valleys. The mountains are expected to receive snowfalls of 4 to 8
inches with the possibility for more if upslope effects are
favorable. This frontal system will be accompanied by gusty winds
with Humboldt county and central Nevada experiencing the strongest
winds. The passage of the cold front will also be the herald of
much colder air moving into Nevada with the rest of the week
expected to much colder than the beginning.

.LONG TERM...Wednesday night through next Sunday. Trough axis
centered along the NV/UT border Wednesday night with cold
northerly flow aloft aligning across western and central NV.
Expecting light snow showers Thursday morning to end from west to
east as trough energy exits east into Utah. A second, weak system,
will bring light snow showers to northeastern NV Friday into
Friday night, however very little additional snow is expected.
Cold and dry conditions across the region Saturday night on
through Christmas with cooler afternoon highs, and much colder
overnight lows.


.AVIATION...Dry with VFR conditions across the region today,
however high and mid clouds will spread in from the northwest.
Winds will be relatively light.
